[PATCH v2 4/5] riscv: dts: starfive: Add phy clock delay configuration for StarFive VisionFive2 board

[Yanhong Wang]

The StarFive VisionFive2 board include 1.2A and 1.3B version.

v1.3B uses motorcomm YT8531(rgmii-id phy) x2, phy clock need delay and
inverse configurations.

v1.2A gmac0 uses motorcomm YT8531(rgmii-id) PHY, and needs phy clock
delay configurations.

v1.2A gmac1 uses motorcomm YT8512(rmii) PHY, and needs to switch rx and
tx to external clock sources.
